摘要： A method (400) and apparatus (300) for selecting one of a plurality of antennas (320, 322), on a UE (300) implementing transmit diversity in a multi-carrier wireless communication system, for the joint transmission of two or more uplink signals, each modulated onto a different carrier frequency, such as when the carriers share a power amplifier (314). The method (400) and apparatus (300) select an antenna (320, 322) based on channel conditions associated with the carriers, even when prior art transmit diversity methods provide conflicting antenna selection indications.

摘要： A NodeB (105) for an HSPA enabled WCDMA network (100), arranged (11, 12, 13) to transmit beam forming instructions to a User Equipment, a UE (1 10), which is arranged for beam forming. The beam forming instructions comprise information identifying a code book with one or more code words, and the NodeB is also arranged to transmit code words from said code book to the UE at a certain rate. The NodeB is further arranged to determine said rate based on dynamically varying information available in the WCDMA network, and to receive said information on the code book from an RNC upon configuration of the U E or to choose code book based on said dynamically varying information available in the WCDMA network.

摘要： The present invention discloses a method in a wireless access network node for controlling a UE. The UE comprises at least two transmit antennas, and is capable of uplink transmit diversity. There is an antenna weight associated with each transmit antenna. First, the wireless access network node determines that the antenna weights of the user equipment may be controlled. Then, it creates a control signal that comprises control information and transmits it to the user equipment. The control information controls a UE autonomous selection of the antenna weights in the UE.

摘要： In a method and a radio base station, the radio base station when receiving a preamble to access one of the E-DCH common resources is adapted to send a NACK even if the default resource for that particular preamble is free. As a result, the UE will monitor the E-AICH and another 'non-default' configuration will be assigned. As a consequence, the default configurations will be the last resources to be assigned.

摘要： The present invention relates to methods and arrangements for uplink retransmissions from a user equipment to a radio base station in a UTRAN with enhanced uplink. The UE transmits a subframe comprising physical control channel(s) and physical data channel(s) in an initial transmission. According to the present invention, one or more of the physical control channels are transmitted with a lower transmission power level in all or some of the retransmitted subframes in the uplink. This results in reduced control overhead (a smaller part of the transmission power resource is used for control signaling) and thus reduced interference from the overhead. At the same time, the transmission power resource no longer used for the physical control channel information, can be used to increase the transmission power level of the physical data channel information in these retransmitted subframes, which improves the uplink coverage.
